I have to confirm that most makers void the warranty on "cosmetic" damage. Next time, scour the warranty to see just what is covered and ask them ahead of time.
For me I'm very protective of my phones and so far, no drops, dings and in a case too.
I purchased a Huawei P9 three months ago. When charging the device yesterday, it started making a loud crackling sound and producing smoke. I turned it off immediately and saw the charging port had burnt up and become pretty mangled; ditto the charger.
I took the phone back to Carphone Warehouse and was informed that because I had a small smash in the corner of the screen the warranty was now totally void and there would be no point sending the phone off to Huawei because they'd just send it straight back. Despite this being a pretty outrageous policy (though unsurprising that they would cover their backs in such a way), I was wondering if anyone had any experience in getting a repair under warranty in spite of cosmetic damage?
I think normally I would probably understand if it was a more standard fault but I think the phone is quite clearly a safety hazard. I had the phone next to me while it was charging so managed to remove the charger at the first sign of malfunction but if I had have left it unattended I'm fairly certain it would have caught fire or exploded. It seems pretty bizarre to me that they would not accept a phone with such a serious fault and there is no way they could connect this to the damaged screen, but the manager at Carphone Warehouse was adamant it wouldn't be considered for repair or replacement.
Any help on this would be greatly appreciated.
